[glass fiber sheets]
In addition, owing to have glass fiber sheets 2, timepiece dial 1 has three-dimensional texture, has the outward appearance of the excellence that did not in the past have.
In addition, the glass material of formation glass fibre generally has the permeability (electromagnetic wave permeability) of excellent electromagnetic wave (electric wave, light).In addition, glass fiber sheets 2 is owing to generally having the space, so have the permeability of excellent especially electromagnetic wave (electric wave, light) between glass fibre-glass fibre.
As the constituent material of glass fibre, for example can enumerate soda-lime glass, crystallinity glass, quartz glass, lead glass, potash glass, pyrex, alkali-free glass etc.
Though the refractive index (absolute index of refraction) to the constituent material of glass fibre limits especially, is preferably 1.40～1.70, more preferably 1.45～1.65, more preferably 1.50～1.60.If the refractive index of the constituent material of glass fibre is the value in the above-mentioned scope, then can make the permeability of electromagnetic wave (electric wave, light) fully excellent, can make the aesthetic appearance of timepiece dial 1 excellent especially simultaneously.
In addition, though the rugosity of the glass fibre that constitutes glass fiber sheets 2 is limited especially, be preferably 1 μ m～20 μ m, more preferably 2 μ m～15 μ m, more preferably 4 μ m～13 μ m.If the rugosity of glass fibre is the value in the above-mentioned scope, then can make the permeability of electromagnetic wave (electric wave, light) fully excellent, can make the aesthetic appearance of timepiece dial 1 excellent especially simultaneously.In addition, can make the stickability of 2 pairs the 1st film the 3, the 2nd films 4 of glass fiber sheets excellent especially.In addition, can make the physical strength (for the stability of distortion) of timepiece dial 1 wait excellence especially.Thereby the permanance of timepiece dial 1 is excellent especially.Relative therewith, if the rugosity of glass fibre is less than above-mentioned lower limit, then the aesthetic appearance as timepiece dial 1 reduces, and simultaneously, electromagnetic wave (electric wave, light) permeability also reduces.On the other hand, if the rugosity of glass fibre surpasses above-mentioned higher limit, then the aesthetic appearance as timepiece dial 1 reduces (particularly being difficult to obtain the higher outward appearance with feeling of high class of whiteness), and simultaneously, the variation range of outward appearance narrows down.In addition, the stickability of 2 pairs the 1st film the 3, the 2nd films 4 of glass fiber sheets also presents the trend of reduction.
In addition, though the surface density of glass fiber sheets 2 is not limited especially, be preferably 20g/m
2～500g/m
2, 40g/m more preferably
2～400g/m
2, 100g/m more preferably
2～300g/m
2If the surface density of glass fiber sheets 2 is the value in the above-mentioned scope, then can make the permeability excellence of electromagnetic wave (electric wave, light), can make simultaneously the aesthetic appearance of timepiece dial 1 excellent especially, in addition, can make the stickability of 2 pairs the 1st film the 3, the 2nd films 4 of glass fiber sheets excellent especially, in addition, can make the physical strength (for the stability of distortion) of timepiece dial 1 wait excellence especially.Thereby the permanance of timepiece dial 1 is excellent especially.
Though the thickness to glass fiber sheets 2 does not limit especially, is preferably 30 μ m～500 μ m, more preferably 50 μ m～400 μ m, more preferably 80 μ m～300 μ m.If the thickness of glass fiber sheets 2 is the value in the above-mentioned scope, then can make the aesthetic appearance of timepiece dial 1 and permanance fully excellent, can make the permeability of electromagnetic wave (electric wave, light) excellent especially simultaneously.Relative therewith, if the thickness of glass fiber sheets 2 is less than above-mentioned lower limit, then because the constituent material of glass fiber sheets 2 etc. are difficult to make the aesthetic appearance of timepiece dial 1 fully excellent.In addition, if the thickness of glass fiber sheets 2 then is difficult to thickness sufficient the 23, the 2nd zone 24, the 1st zone described later is set, thereby may be difficult to improve fully the permanance of timepiece dial 1 less than above-mentioned lower limit.On the other hand, if the thickness of glass fiber sheets 2 surpasses above-mentioned higher limit, then the thickness as timepiece dial 1 integral body increases, and is for example, when being applied to clock and watch described later, unfavorable to the slimming of clock and watch.In addition, if the thickness of glass fiber sheets 2 surpasses above-mentioned higher limit, then, be difficult to be applied to suitably sun power clock and watch (being embedded with the clock and watch of solar cell), radio controlled timepiece etc. because the constituent material of glass fiber sheets 2 etc. have reduced the electromagnetic transmitance as timepiece dial 1.
In addition, glass fiber sheets 2 can by such as plain weave, tiltedly knit, any textile material such as satin weave, lace stitch, piquet constitutes, and in addition, also can be by constituting such as non-nonwoven fabric of knitting etc.Wherein, be preferably the glass fiber sheets that constitutes by textile material, more preferably the glass fiber sheets that constitutes by the textile material that utilizes plain weave to be made into.In view of the above, can make the aesthetic appearance of timepiece dial 1 excellent especially.
The 1st film 3 is arranged at the 1st 21 1 sides as an interarea of glass fiber sheets 2.In addition, the 2nd film 4 is arranged at the 2nd 22 1 sides of another interarea (with the interarea of the 1st 21 opposite sides) as glass fiber sheets 2.
And, in the glass fiber sheets 2, have the 1st zone 23 at the 1st 21 near surface, and at least a portion of the 1st film 3 enters the 1st zone 23, in addition, have the 2nd zone 24, and at least a portion of the 2nd film 4 enters the 2nd zone 24 at the 2nd 22 near surface.
So, by surface, can make the physical strength excellence of timepiece dial with film cover glass fibre plate.And, among the present invention, because the part that film has entered the thickness direction of glass fiber sheets, so the stickability excellence of glass fiber sheets and film.Especially, because in glass fiber sheets, the complexing of glass fibre phase, so by film is entered between glass fibre-glass fibre etc., can bring into play anchoring effect effectively, the stickability of glass fiber sheets and film is excellence especially.Therefore, can keep excellent physical strength long-term and stably.In addition, because the surperficial tunicle (the 1st film and the 2nd film) of glass fiber sheets covers, has the structure of a part that film enters the thickness direction of glass fiber sheets, so can prevent effectively that the glass fibre that constitutes glass fiber sheets from bursting forth.Thereby can prevent reliably for a long time because the reduction of the aesthetic appearance of bursting forth the timepiece dial that is caused of glass fibre.In addition, can guarantee to prevent since burst forth glass fibre caused that movement etc. is produced harmful effect, can make the reliability of clock and watch excellent especially.
In addition, by film being arranged on the surface of glass fiber sheets, can obtain following effect.Promptly, glass fiber sheets is owing to be made of a large amount of glass fibre, so intrinsic from the teeth outwards bigger fluctuating, be difficult to print, set up type (install timing numeral), processing such as adhesion timing numeral, in addition owing to be difficult to improve fully the stickability of these literal, therefore be difficult to be applicable to timepiece dial, by as mentioned above, on the surface of glass fiber sheets, film is set, can be easily and carry out above-mentioned processing reliably.
In addition, this film (being that its part has entered the film of a part of the thickness direction of glass fiber sheets at least) is arranged at the two sides of glass fiber sheets.Therefore, can prevent effectively when producing temperature variation etc., because the generation of the bending of the not equal timepiece dial that causes of the thermal expansivity between the constituent material of the constituent material of film and glass fiber sheets etc.That is,, can make the excellent in stability of the shape of timepiece dial owing on the two sides of glass fiber sheets, have film.
Though the thickness in the 1st zone 23 is different and different according to the thickness of glass fiber sheets 2, the thickness in the 2nd zone 24 etc., is preferably 0.1 μ m～140 μ m, more preferably 0.2 μ m～80 μ m, more preferably 0.5 μ m～30 μ m.If the thickness in the 1st zone 23 is the values in the above-mentioned scope, then can make the aesthetic appearance of timepiece dial 1 fully excellent, can make simultaneously the stickability of glass fiber sheets 2 and the 1st film 3 excellent especially, can make the permanance (stability of physical strength, shape etc.) of timepiece dial 1 excellent especially.Relative therewith, if the thickness in the 1st zone 23 is less than above-mentioned lower limit,, be difficult to fully improve the stickability of glass fiber sheets 2 and the 1st film 3 then because the constituent material of the 1st film 3 etc., be difficult to improve fully the permanance of timepiece dial 1.On the other hand, if the thickness in the 1st zone 23 surpasses above-mentioned higher limit, then owing to the thickness of glass fiber sheets 2, the thickness in the 2nd zone 24 etc., the thickness in the 3rd zone 25 described later reduces, and the aesthetic appearance of timepiece dial 1 shows the trend of reduction.
In addition, though the thickness in the 2nd zone 24 is different and different according to the thickness of glass fiber sheets 2, the thickness in the 1st zone 23 etc., be preferably 0.1 μ m～140 μ m, more preferably 0.2 μ m～80 μ m, more preferably 0.5 μ m～30 μ m.If the thickness in the 2nd zone 24 is the values in the above-mentioned scope, then can make the aesthetic appearance of timepiece dial 1 fully excellent, can make simultaneously the stickability of glass fiber sheets 2 and the 2nd film 4 excellent especially, can also make the permanance (stability of physical strength, shape etc.) of timepiece dial 1 excellent especially.Relative therewith, if the thickness in the 2nd zone 24 is less than above-mentioned lower limit,, be difficult to improve fully the stickability of glass fiber sheets 2 and the 2nd film 4 then because the constituent material of the 2nd film 4 etc., be difficult to improve fully the permanance of timepiece dial 1.On the other hand, if the thickness in the 2nd zone 24 surpasses above-mentioned higher limit, then owing to the thickness of glass fiber sheets 2, the thickness in the 1st zone 23 etc., the thickness in the 3rd zone 25 described later reduces, and the aesthetic appearance of timepiece dial 1 shows the trend of reduction.
In addition, glass fiber sheets 2 not only has the 23, the 2nd zone 24, above-mentioned the 1st zone, also has the 3rd zone (air layer) 25 in the 1st zone between the 23 and the 2nd zone 24, and the 1st film 3 and the 2nd film 4 do not enter the 3rd zone 25.In the 3rd zone 25, the glass fibre that constitutes glass fiber sheets 2 is covered by atmosphere gas such as air usually.General this atmosphere gas has than the abundant little refractive index (being about 1.001) of the material that constitutes glass fibre.
So, the zone (the 3rd zone) by the constituent material that makes glass fiber sheets have film on its thickness direction does not enter can make outer light diffuse reflection effectively, can make the aesthetic appearance of timepiece dial excellent especially.Relative therewith, if do not have the 3rd zone, then can not carry out the diffuse reflection of outer light etc. effectively, can not obtain the aesthetic appearance of the excellence that glass fiber sheets has.Be described in detail below, if do not have the 3rd zone, then timepiece dial itself is transparent too high, when seeing a face (interarea) side of timepiece dial, pass through timepiece dial, seen the appearance of its opposite face (interarea) side, thereby the aesthetic appearance of glass fiber sheets timepiece dial reduces significantly.This be possible be because, the refractive index that the constituent material of the 1st film the 3, the 2nd film 4 has is usually significantly greater than gases such as air, the refractive index with glass fibre has little difference usually, thereby has prevented owing to the diffuse reflection of the caused outer light of glass fibre etc.In addition,, reduced the transmitance of light significantly this moment, can not be applicable to sun power clock and watch described later etc. though, can expect to use the constituent material as timepiece dial such as relatively large colorant in order to prevent the problems referred to above.In addition, when having used relatively large colorant, timepiece dial does not have feeling of high class, and aesthetic appearance is relatively poor.
Though the thickness to the 3rd zone 25 does not limit especially, is preferably 5 μ m～280 μ m, more preferably 30 μ m～260 μ m, more preferably 79 μ m～245 μ m.If the thickness in the 3rd zone 25 is the values in the above-mentioned scope, then when the permanance that can make timepiece dial 1 is fully excellent, can make the aesthetic appearance of timepiece dial 1 excellent especially.Relative therewith, if the thickness in the 3rd zone 25 is less than above-mentioned lower limit, then because the constituent material of the 2nd film 4, thickness etc. may be difficult to make the aesthetic appearance of timepiece dial 1 fully excellent.On the other hand, if the thickness in the 3rd zone 25 surpasses above-mentioned higher limit, then, be difficult to improve fully the permanance of timepiece dial 1 because the thickness of glass fiber sheets 2 etc. are difficult to make the thickness in the 23, the 2nd zone 24, the 1st zone enough big.In addition, when the thickness in the 3rd zone 25 surpasses above-mentioned higher limit, owing to increased the thickness in the 23, the 2nd zone 24, the 1st zone, thereby the thickness of glass fiber sheets 2 increased, at this moment, thickness as timepiece dial 1 integral body increases, make when for example being applied to clock and watch described later, unfavorable to the slimming of clock and watch, in addition, electromagnetic transmitance as timepiece dial 1 reduces, and may be difficult to be applied to suitably sun power clock and watch, radio controlled timepiece etc.
